Multi Blade Block Cutter

This 80-blade gangsaw is characterized by the raising of the block during the sawing phase.
General characteristics:
Flywheel in two halves diameter 3.5m.
Main battery shaft and crank made of high resistance forged steel, rotating in high quality spherical roller bearings.
The main plummer block, made of cast steel, is completely immersed into the concrete, providing a very strong anchorage to the foundations thus enabling an operation free of vibrations which are dangerous to the machine and the diamond blades.
The main motor is powered through a soft starter to control the starting speed and time.
The connecting rod, made of high quality steel, guarantees a high resistance to the dynamic stresses generated.
The main frame is totally fabricated from high strength steel, dimensioned to guarantee an absolute rigidity and stability under load.
The sliding system is made of specially designed sliders, completely immersed in oil.
The motorized block carrying trolley enters the machine from the front side and is automatically locked to the lifting platform as it starts to lift. This lifting motion is driven by steel screws and alloyed nuts with trapezoidal threads, amply dimensioned. The sliders on the columns, prismatic and flat, are made of Teflon. The whole lifting system is protected by polyurethane bellows.
The lifting platform speed variation is achieved by a group of gearboxes and clutches controlled by an inverter.
The nuts and sliders of the lifting platform are equipped with safety devices that stop the machine as soon as the wear becomes excessive.
The machine stops automatically if there is a drop of pressure in the cooling water.
The main chassis is equipped with a set of steps and passage ways, anti-slip and anti-accidents with pipe rails all around, to allow access to the top part of the machine.

This machine distinguished essentially by many innovative design and technological solutions realized through high level experience and knowledge of the problems met in the use of granite gang saws and well known by the Designer and Mordenti, has solved the sawing requirements allowing very high hourly feeds (almost triple) on class 4 granites using normal blades and metallic grit. It is thus a realization which represents a cooperation between the experience of the technicians of this field and Mordenti, a Company distinguished by the high construction reliability, which has allowed to increase considerably the hourly output of the granite gang saws, to assure machine functionality in the long run, equip it with automatic lubrication, operation and control systems together with suitable structures of the various components which guarantee limited investement and maintenance costs in relation to the production achievable.
The important innovation and technological heart of the machine is the interesting patented mechanical application which allows the blade frame to be lifted and fed several times with the normal abrasive mixture during its wide rectilinear cutting phase and give contemporaneusly a percussion action in the descent phase.
The combination of the lifting stroke and force action is adjustable in intensity and frequency depending on the material that is being sawn and the hourly feeds required. Furthermore, at the ends of the stroke, the blade frame rises much more than the other present gangsaws and this increases the feed of the abrasive mixture, all flexible and integrated to the results one wants to achieve.
The combination and use of these three factors has brought a considerable advantage to granite sawing without being particularly burdensome but as a matter of fact allowing to increase remarkably the hourly feed and the sawing time of the block by bringing a considerable technological development to this field in connection with the modern production systems and absolute cutting precision also for 11 mm. thick slabs.
The movement of the blade frame is clearly different from those presently on the market as with the patented system the stroke of rectilinear movement is adjustable and there is wide lifting in the reversal points. This allows greater contact between blades and block and a considerable supply of the abrasive mixture due to adjustable amplitude of the rectilinear stroke and rise of the blade frame.
The patented device which eliminates the oscillating arms, silentblock and other infrastructures relative to the traditional gang saws is made up of a sector with variable radius of curvature with counter part on tempered flat guide with relative gears for the phasing of the blade frame movement. All is held in proper boxes in oil bath arranged at the ends of the frame members together with other particulars that with very rational and simple solution assure rectilinear movements of the blades and high removing capacity in time. This solution also allows to have shorter columns considering blocks of the same height. The main features that highlight the gang saw Turbomord are:
1) High reliability and design with relevant technological innovations, respecting however the traditional concept of granite sawing.
2) Automatic closed circuit oil lubrication system.
3) Control board with logic P.L.C. program.
4) Elimination of the connecting rod adjustment in the feed stages.
5) Almost absolute absence of maintenance.
6) Design in compliance with the environmental protection rules due to absence of oily residuals and for the possibility to install soundproof panels on request.
